investing in research and development spending (r&d) affects total factor productivity (tfp).recently new theories of economic growth have emphasized the relationship between r&d and tfpand also identified a number of channels through which a country’s r&d affects tfp of its tradepartner. this study seeks to estimate the effect of agricultural r&d and education spending and some...

A shear-lag model has been developed for the prediction of stress recovery in a broken ®ber embedded in a ductile-matrix composite. The model builds on the original shear-lag model of (Cox HL. Br J Appl Phys 1952;3:72±9) by introducing plasticity constitutive behavior into the matrix. The matrix is assumed to be an elastic/perfectly-plastic material that deforms according to J2 ̄ow theory. The ...

Lag synchronization is a basic phenomenon in mismatched coupled systems, delay coupled systems, and time-delayed systems. It is characterized by a lag configuration that identifies a unique time shift between all pairs of similar state variables of the coupled systems. In this report, an attempt is made how to induce multiple lag configurations in coupled systems when different pairs of state v...

In the last twenty years, analysis of problems involving dual-phase-lag models has received an increasing attention. this work, we consider coupling between one these and microtemperatures effects. order to overcome infinite speed paradox, two relaxation parameters are introduced for each evolution equation related temperature microtemperatures, leading a system linear hyperbolic partial differ...

The objective of this paper is to investigate the long-run and short-run relationships among tourist arrivals to Malaysia and tourism price, substitute price, travelling cost, income and exchange rate for Asian7. The autoregressive distributed lag (ARDL) bounds test approach developed by Pesaran et al. (2001) is employed in the analysis, and the data cover the period 1970 to 2004. The empirical...

This paper examines the monetary transmission mechanism in the countries of the Central African Economic and Monetary Community (CAEMC). Specifically, we focus on the very first step of this mechanism namely the interest rate pass-through from short-term interest rates towards long-term rates. Using an autoregressive distributed lag (ADRL) model, we show that there is evidence of a very low and...
